You're recycling your milk carton all wrong

Milk cartons are made primarily of paper but also have a thin layer of polyethylene. As such, they should be recycled with plastic, metal, and glass.

milk recycling

Many people don't know how to recycle milk cartons, as evidenced by this photo of three milk cartons erroneously placed in the paper bin at my office.

Here's the truth, taken straight from the Carton Council (the main organization for carton manufacturers in the US):

Cartons are made primarily of paper but also have a thin layer of polyethylene, or plastic. Shelf-stable cartons contain a layer of aluminum. As such, milk cartons should be recycled with plastic, metal, and glass containers. Ultimately, the cartons will be sorted separately at the recycling facility and disposed of properly.
